Description

Technical Field

[0001] This utility model relates to the field of vacuum aluminizing technology, and in particular to a vacuum vapor phase aluminizing furnace with uniform heating. Background Technology

[0002] A vacuum vapor phase aluminizing furnace is an industrial furnace specifically designed for vapor phase aluminizing under vacuum and a specific atmosphere. It heats aluminum powder to a high temperature, causing it to evaporate and deposit on the surface of a substrate to form an aluminum layer. Then, at a high temperature, the aluminum layer is dispersed onto the surface of the substrate to form a composite layer that is chemically bonded to the substrate, thereby improving the metal's high-temperature oxidation resistance and resistance to gas corrosion.

[0003] Existing vacuum aluminizing furnaces, which provide uniform heating, mostly require manual opening of the cover. Operators need to directly contact the high-temperature furnace body, posing safety hazards such as burns. In addition, if the pressure inside the furnace is not fully released or the temperature has not dropped to a safe range, manually opening the cover may lead to accidents.

[0004] Therefore, while existing vacuum v-phase aluminizing furnaces can achieve uniform heating, most require manual opening of the cover, posing safety hazards such as burns due to direct contact with the high-temperature furnace body. Furthermore, manual opening can lead to accidents if the furnace pressure is not fully released or the temperature has not dropped to a safe range. A solution is to design a vacuum v-phase aluminizing furnace with uniform heating that automatically opens and closes the cover when necessary, improving efficiency and safety. This would solve the problems associated with manual cover opening, direct contact with the high-temperature furnace body, burn hazards, and accidents if the furnace pressure is not fully released or the temperature has not dropped to a safe range. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a vacuum gas phase infiltration furnace with uniform heating. This furnace aims to solve the technical problems of existing technologies, where most furnaces require manual opening of the cover, which requires operators to directly contact the high-temperature furnace body, posing safety hazards such as burns. Furthermore, if the pressure inside the furnace is not fully released or the temperature has not dropped to a safe range, manually opening the cover may lead to accidents.

[0013] The beneficial effects of this invention are as follows: Compared to traditional vacuum aluminizing furnaces that provide uniform heating, most of which require manual opening of the cover, operators need to directly contact the high-temperature furnace body, posing safety hazards such as burns.

This device, through an automatic switch, can automatically open and close the cover when needed, improving work efficiency and safety. This solves the problems of manual opening of the cover, requiring operators to directly contact the high-temperature furnace body, posing safety hazards such as burns, and the potential for accidents if the furnace pressure is not fully released or the temperature has not dropped to a safe range.
